comorbidity
Additional diseases or conditions that occur alongside obesity, often improved or resolved after bariatric surgery.
Full Definition
In bariatric surgery, comorbidities refer to obesity-related health conditions that may improve or resolve following weight loss surgery. Major comorbidities include type 2 diabetes mellitus, hypertension, obstructive sleep apnea, dyslipidemia, gastroesophageal reflux disease, and cardiovascular disease. The presence of significant comorbidities lowers the BMI threshold for surgical candidacy from 40 to 35 kg/m². Resolution or improvement rates vary by procedure and comorbidity type, with diabetes showing particularly high resolution rates after metabolic surgery. Comorbidity improvement is a key outcome measure beyond weight loss alone.
Usage
Usage note: Use singular 'comorbidity' or plural 'comorbidities' appropriately. Avoid 'comorbid conditions' as redundant.
